[0028] like Figure 1 and Figure 2 As shown, the utility model designs a door glass detection automatic control system, which includes: a power supply unit and a solenoid valve control unit, a data acquisition unit and a data storage unit electrically connected to the power supply unit; wherein the above-mentioned data acquisition unit is communicatively connected to the data storage unit, and the above-mentioned solenoid valve control unit is used to control the air intake or exhaust of the solenoid valve to control the movement of the cylinder and adjust the position of the door glass; the above-mentioned data acquisition unit is used to measure the door glass and obtain door glass detection data, so as to send the detected door glass detection data to the data storage unit communicatively connected thereto, and at this time the data storage unit can be used to receive and store the above-mentioned door glass detection data, so as to facilitate the R&D personnel to subsequently analyze and trace the quality problems of the door glass product.

[0029] It should be noted that, in this embodiment, the solenoid valve control unit of the door glass detection automatic control system specifically includes: a PLC controller, a time relay and an intermediate relay; wherein, the above-mentioned PLC controller is electrically connected to the time relay and the intermediate relay respectively, and the intermediate relay is electrically connected to the solenoid valve, and the two can be specifically connected through a signal line.

[0030] In the present invention, the time relay in the solenoid valve control unit is used to count the time and send the time count to the PLC controller. The time relay can be used to reserve time for the next control action, thereby realizing time interaction between logical actions and preventing disorder in logical actions.

[0031] Accordingly, the PLC controller receives the time count and sends a corresponding action signal to the intermediate relay. The intermediate relay receives the action signal and outputs a control instruction to the solenoid valve to control the air inlet or outlet of the solenoid valve, thereby indirectly controlling the cylinder movement and adjusting the detection position of the door glass. In this embodiment, the PLC controller can be specifically a Siemens PLC controller, which is the core component of the solenoid valve control unit and sends all control signals.

[0032] Furthermore, in the present invention, considering that the door glass detection tooling used in the door glass detection automatic control system is often connected to a 220V AC mains power grid, the door glass detection automatic control system may also be provided with an AC power supply and an AC / DC converter. The AC power supply is electrically connected to the AC / DC converter, and the AC / DC converter is electrically connected to the solenoid valve control unit, the data acquisition unit, and the data storage unit, respectively. Furthermore, an air switch is provided in the circuit to control the power on and off of the circuit and to provide overload protection.

[0033] Of course, in some other embodiments, the power supply unit may be directly configured and selected as a low-voltage DC power supply, and the low-voltage DC power supply may be directly electrically connected to the solenoid valve control unit, the data acquisition unit, and the data storage unit. In this case, the operator can use the low-voltage DC power supply to directly power each unit in the automatic control system.

[0034] Accordingly, in the door glass detection automatic control system designed in the present invention, the data acquisition unit may specifically include a data collector and a communication module.

[0037] Furthermore, it should be noted that in the automatic door glass detection control system of the present invention, the data storage unit may specifically include: a data processor and a database. The data processor is connected to the database and is configured to receive and process acquired door glass detection data, while the database is configured to store the processed door glass detection data. For example, in this embodiment, the data processor may receive the door glass detection data and process it into an Excel file format, which is then saved in a predetermined storage path.

[0038] In addition, another purpose of the present invention is to set up a door glass detection tooling, which includes a profiling mold, a cylinder and the above-mentioned door glass detection automatic control system of the present invention. By using this door glass detection tooling, the profiling mold can be used to place the door glass to be inspected, and the above-mentioned door glass detection automatic control system can be used to control the movement of the above-mentioned cylinder to adjust the door glass to be inspected to the station to be inspected, so as to inspect the door glass and obtain door glass detection data, and automatically save the door glass detection data.

[0039] Accordingly, if Figure 2 As shown, Figure 2 The circuit connection relationship of the above-mentioned door glass detection tool is disclosed. Figure 2 In the figure, S1 normally open contact is for manual or automatic mode switching, S2 normally open contact is for function selection, S2 normally closed contact is for foot switch input signal, K4 normally open contact is for saving completion, S3 normally open contact and S4 normally open contact are for magnetic switch input signal, which can predict whether the cylinder is in place and thus ensure the safety of the equipment. The output signals are intermediate relays K1, K2, K3-K6, and the corresponding functions are probe extension or retraction, data signal storage, pressing or extension of the spinning cylinder, travel or return of the slide cylinder, and finally the action of the time relay closing or opening.
